Looking at job ads over the years though for me, it does seem like "if you want London wages, go to London"- saying that from one of the lower paid parts of the UK. Wonder how the FB employees will react, is a part of it the 'prestige' of being a high dollar earner, in an 'elite' neighbourhood or is it about quality of life. Maybe a lot of these social barriers will start shifting the next 12/24 months.
